What is an annulus? Pupils first learn about how to create an annulus, then consider how to find the area of such shapes. They then complete a problem set on arc length and areas of sectors.

It's not just any circle—it's the unit circle. The fourth lesson in the series is an introduction to the famous unit circle. While working through a series of activities, young scholars learn the components of the unit circle and how to...

General chemistry class members engage in a mini-unit on mole conversions. Through nine lab activites with varying degrees of difficulty, they practice measuring mass and volume, molar calculations, and stoichiometry. Terrific...

Mr. Snowman wants to help emerging readers understand compound words, so he segments some familiar words to help them see that they are made of two distinct words. Learners repeat the words, both segmented and blended, and observe them...

Explore the harsh climate of Antarctica and its wildlife. Participate in experiments to determine how humans survive in the continent's climate, and address the difficulties faced by scientists.

Sometimes being different is an advantage. An engaging activity has scholars match cards with quadratic functions in various forms. Along the way, they learn about how each form highlights key features of quadratic functions.

This is the ticket to learning about function rules! Using online manipulatives, scholars build a table of values and then answer questions about the related function. They examine the relationship between the input and output values and...

Learning isn't a random process. A well-designed interactive lesson helps classes make key conclusions about stratified random sampling. They calculate group percentages and use those percentages to decide on sampling totals.

Although written for middle schoolers, there is no reason that a 3rd, 4th, or 5th grader could not also learn about food chains through the dissection of owl pellets. After you introduce the topic, learners complete an owl research...

How do graphic designers project three-dimensional images onto two-dimensional spaces? Scholars connect their learning of matrix transformations to graphic design. They understand how to apply matrix transformations to make...

Fifth graders explore electrical concepts and host a guest speaker. This lesson sets up guidelines for students to follow when they have a guest speaker. Students are primed to become actively involved in a lecture or discussion, while...

Here is an exciting exploration of a fascinating topic for your emerging ecologists: bird migration! They begin by visiting the US Fish & Wildlife Service website to discover which Arctic birds come to their areas. They are assigned...

Satellites require rockets to launch, but it doesn't take a rocket scientist to understand them. Future engineers learn about how satellites send data to Earth and how to interpret satellite images. They see how radio waves play a role...

What do fractions and rational expressions have in common? Everything! Learners use common denominators to solve rational equations. Problems advance from simple to more complex, allowing pupils to fully understand the material before...

Students examine speech difficulties by reading a children's book in class. In this children's literature lesson, students read the story Hooway for Wodney the Wat, and analyze the characters, story and the bullying that takes place....

Students read about Humane Genome Project, examine structure and function of DNA, and participate in gel-electrophoresis lab. They complete Internet activity to test their knowledge of DNA.

Students examine the impact that humans have had on the environment and the difficulties the environment can cause. They also examine major physical changes as a result of human action or natural causes.

Through this set of three lessons about Ellis Island, class members will learn about why immigrants came to the United States, find out about the difficulties that went along with coming to America, become familiar with the immigration...

Students explore fish. In this aquatic life science lesson, students complete a KWL chart about fish, listen to What's it Like to be a Fish?, and observe a classroom aquarium or take a trip to a local aquarium. Students complete an...

After collecting carbon dioxide bubbles from a cup of club soda, learners attempt to make their own lemon soda while preventing the loss of carbonation. They do so by creating a syrup before mixing the substances into the club soda....

Eighth graders put their knowledge of rocks and minerals into perspective by seeing how minerals can be mined and the difficulties and costs of mining. They explore the environmental impacts of mining.

Students learn how to measure the density of metals. In this density of metals lesson plan, students measure the density of various metals in order to determine what metals were substituted in a king's crown, scepter, breast plate and...
